IMAGE DISPLAYING METHOD FOR DETECTING DAMAGE IN COMPOSITE MATERIALS EMBEDDED WITH FIBRE OPTIC NETWORK

The image displaying method, showing damage in fibre optic network embedded in composite materials, is studied. And a corresponding detection system has been made. By digitally processing the image which carries all the information exported by the network, damage in composite materials can be quantitatively detected and directly displayed. The results of the impact damage tests proved that the fibre optic image system has many advantages compared with ordinary photo electric detecting systems.
